ICC-ES AC503
Full Name
ICC-ES AC503 – Acceptance Criteria for Adhered Porcelain Tile Wall Cladding System
Scope
ICC-ES AC503 outlines the acceptance criteria for evaluating the performance of adhered porcelain tile wall cladding systems. This includes the assessment of the following components and their interaction:
- Porcelain tiles: their physical properties, dimensions, and water absorption rate.
- Bonding materials: mortars or adhesives used to adhere the tiles to the substrate.
- Substrates: the underlying surface to which the tiles are bonded, such as concrete, masonry, or gypsum board.
The evaluation process typically involves laboratory testing to assess the system’s resistance to various factors, including:
- Shear bond strength: the ability of the tile to remain bonded to the substrate under stress.
- Freeze-thaw resistance: the ability of the system to withstand repeated cycles of freezing and thawing without deterioration.
- Water penetration resistance: the ability of the system to prevent water from penetrating behind the tiles.
- Impact resistance: the ability of the system to withstand impact without cracking or debonding.
ICC-ES AC503 is primarily used by ICC Evaluation Service (ICC-ES) to issue evaluation reports to applicants. These reports confirm that a specific adhered porcelain tile wall cladding system meets the specified performance criteria.
